Letters Patent No. 96,368, dated November 2, 1869.

STEAM WATER-ELEVATOR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'

Be it known that I, J AMES D. WARNER, of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful Improvement in Water-Elevators; and I do hereby declare that the fcllowingis a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvement in apparatus for elevating water, by the action of the vacuum formed by the condensation of the steam, for raising the water into a receiver, and by the direct pressure of the steam in forcing the water from the receiver through the discharge-pipes.

The invent-ion comprises the arrangement, in a pair of vertical parallel tubes, connected at the bottom, and having a condenser, suction, and discharge-pipe connections, and a heater, of an improved automatic valve-arrangement, operated alternately by water and gravitation, for opening and closing the steam-passage from the. top of one of the tubes, where the steam is generated, to the top of the other, where it is condensed and a vacuum formed.

The invention also comprises an arrangement of a piston, and certain adjunct-s in cach tube, to insure a prompt return of the water to the generator, and to prevent 'the advance, as much as possible, of the hot water in the condenser.

Figure 1 represents a sectional elevation of my improved apparatus, and

Figure 2 represents a detail view of the surfacecondensing coil, and

Figure 3 represents a modied arrangement of heating-apparatus.

A and A1 represent a pair of large vertical parallel tubes, of about the same height, united by a connection, A2, at the bottom.

B is a furnace, arranged at the top of A.

C is a condensing-coil in the top of A.

D, a section of pipe, connected with A1, and leading to .the well. AIt isv provided with a check-valve, E,

opening upward.

F is a discharge-pipe, leading from the top of A1, also provided with a check-valve, G, opening upward.

H is a steam-pipe, leading from the top of A to the top of Af. It is-provided in A with a valve, K, having a long stem, arranged to be ilo-ated by the water, projecting downward, and provided with stops, M N, and an empty bi1Ib, O, sliding between the two stops.

When fire is applied to the furnace, the tubes A, A, and A2. being previously filled with water, steam will be generated around the furnace, which, as it increases in volume, will force the water down vin A,

through A1 and A2, and out througl1 the pipe F.

During this time, the valveK, which was closedv when the filling oi' the tube A tookl place, by the,

rising of the bulb against the stop; M, will remain closed until .the water falls so low in A that the weight of the bulb bears upon the stop N and opens the valve, and the steam' having access to the top of A1, the water therein' will flow back into A, leaving the space around the condenser to be filled with steam, which, soon condensing, causes a vacuum, which will be lilled through the suction-pipe D; the water rising in A forces the bulb against the stop M, again closing the valve K, by which the steam will be again accumulated in A, and the above-described operations will then be repeated as long as fire is kept in the furnace.

P represents a hollow piston in the pipe A, having a hole through it, -to which is attached the valve Q, opening upward. It are guide-rods, wberen it works up and down. They have also stops S, to limit the movement of the piston.

Tis a xed rod, for insuring the opening of the valve when the piston arrives at or near the end of its downward movement.

P is a solid piston, similarly arranged in the tube A, with guide-rods R and stops S', and having a. valve, Q', opening downward, also a rod, T', for insuring the opening of the .valvef This piston is also, it' required, weighted'by' a rod, U, and weight V, the said rod passing down through the tube A2 in a suitable stufing-box. v

The oiice of these pistons is to canse the immediate return of the water from the condensing-tube to the furnace; the one, P', being heavy, will, by its weight,

accelerate the movement of the valve, and the other being hollow, and consequently lighter than the water, will cause the water above it to rise. They will be carried back by the water, when it is forced into A. They are also intended to prevent acirculation of water, so that the heated water will not comev into contact with the condenser.

I propose to dispense with the pistons, or use one or more with or without their adjuncts, or any part of them, as may befound necessary to the accomplishment of the .object desired.

Instead of the employment of the heater at the top of A, for generating steam, the steam may be snp'- plied from any other source through 'a pipe, W, or, dispensing with a dre-box, heat may be thrown against the tube A, or'some enclosed space connected with A, as in ig. 3, where g g is a circular ring, perforated at the top, through'which burning gas or uid is pro jected against the hollow disk H, connected to the tube A by the tube T'.

Having thus described my invention,

I claim as new, and' desire to secure by Letters Patent- The combination, with a heater and condenser, arrangedl substantially as described, of a cut-oft' valve, arranged to be operated by the action of water and gravity for opening and closing the passage from thev generator to the condenser, substantially as specied.

Also, the combination, with the generator and condenser, of one .or more pistons, to urge and regulate the return of the Water to the generator, either with or without the valves, guides, and Weight, or any of them, substantially as described.

Also, the combination of the generator, condenser, automatic valve-device, and pistons, either with their valve and weight V or not, substantially as specified.

The above specification of my invention signed by me, this 14th day of August, 1869.

JAS. D. WARNER.
